Only older versions of windows is affected - Win8 and earlier, so Win10 is safe.And you get owned by wannacry, don't cry... You only brought it on yourself by being opposed to forced updates!
Suckers.
I've disabled windows update on my slower Win10 pc since it can become excessively slow and rely on 3rd party AV to catch things. I prefer to let other people be the guinea pigs for bigger feature updates and its worked out well for me.
